Description
Currently, you can parse a file and get a WavefrontOBJ with the fromFile
function.

Vertex location
A location is a 4-floating vector. You can access to its components by pattern matching on them:
let Location x y z w = Location 1 2 3 4
That type is strict and unboxed.
Vertex texture coordinates
A texture coordinate is a 3D-floating vector. You can access to its components by pattern matching on them:
let TexCoord r s t = TexCoord 0.1 0.2 0.3
That type is strcit and unboxed.
Vertex normals
A normal is a 3-floating vector. You can access to its components by pattern matching on them:
let Normal nx ny nz = Normal 0.1 0.2 0.3
That type is strict and unboxed.
Points
A point is a single index that references the locations. It’s a canonical type that truly represents a polygonal point.

Fields | |
A line index is a pair of indices. LineIndex vi vtivi references the locations and vti
indexes the texture coordinates. If vti == , then that NothingLineIndex doesn’t have
texture coordinates associated with.

Faces
A face gathers several FaceIndex to build up faces. It has a least three vertices
A face index is a triplet of indices. FaceIndex vi vti vnivi, the texture coordinates with vti and the normals with vni. An index set
to Nothing means no information. That is, if vni == , then that NothingFaceIndex
doesn’t have a normal associated with.

Element
An element holds a value along with the user-defined object’s name (if any), the associated groups, the used material and the smoothing group the element belongs to (if any). Those values can be used to sort the data per object or per group and to lookup materials.
